Compressor motor shuts off after 20 seconds.
I have a Craftsman oil-less compressor, 6hp 33 gallon with an AO Safety motor. It runs for 20 seconds and then trips my surge protector. I am running motor only, the piston and such are not hooked up. I tried to replace the capacitors..cheap fix..it's not them. The motor runs the same even with the capacitors NOT plugged in. Everything is clean, no broken or burned wires. I did notice a round (sensor or pick-up of some sort?), quarter size component that is attached to the back of the motor body that gets pretty hot to the touch but I don't know if its replaceable or what it's true function is.
Mike, if it's tripping the surge protector then it's pulling more amps than the circuit can handle. It's not clear from your comment (at least to me) if it's tripping out after 20 seconds when it's not coupled to the pump.
Regardless, to me it sounds like an electrical fault, and the motor is the likely culprit. Get it checked, would be my advice.
i have a craftsman air compressor - then wont restart
new presure switch and it turns on and builds presure then shuts off at 175 . then wont restart without blowing the breaker
Is the unloader valve working?
